Even though the circuit appears as high impedance to the external source, there is a large current circulating in the internal loop of the parallel inductor and capacitor. An overdamped series RLC circuit can be used as a pulse discharge circuit. Often it is useful to know the values of components that could be used to produce a waveform.
An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.
In the case of the series RLC circuit, the damping factor is given by The value of the damping factor determines the type of transient that the circuit will exhibit. Plot showing underdamped and overdamped responses of a series RLC circuit to a voltage input step of 1 V.
The RLC filter is described as a second-order circuit, meaning that any voltage or current in the circuit can be described by a second-order differential equation in circuit analysis. The three circuit elements, R, L and C, can be combined in a number of different topologies.
To analyze a series RLC circuit, follow the same approach as for series RL and RC circuits. However, this time, consider the magnitudes of both XL (inductive reactance) and XC (capacitive reactance) to find the overall circuit reactance.
The series RLC circuit has a sinusoidal response that varies with frequency, ƒ. This is because the inductive and capacitive reactances, XL and XC, are functions of the supply frequency.
Parallel RLC Circuit The RLC circuit shown on Figure 6 is called the parallel RLC circuit. It is driven by the DC current source Is whose time evolution is shown on Figure 7.

Figure 14.17 (a) An RLC circuit. Electromagnetic oscillations begin when the switch is closed. The capacitor is fully charged initially. (b) Damped oscillations of the capacitor charge are shown in this curve of charge versus time, or q versus t. The capacitor contains a charge q 0 q 0 before the switch is closed.
L''amortissement, dans un circuit RLC série en régime libre (sans apport extérieur d''énergie), dépend de la résistance totale du circuit : Rt = R + r . a. Régime pseudo-périodique : Celui-ci est observé quand l''amortissement est faible c''est à dire quand la valeur de Rt est petite .

In this section we consider the (RLC) circuit, shown schematically in Figure 6.3.1 . As we''ll see, the (RLC) circuit is an electrical analog of a spring-mass system with damping. Nothing happens while the switch is open (dashed line). When the switch is closed (solid line) we say that the circuit is closed. Differences in electrical ...
When the switch is closed in the RLC circuit of Figure (PageIndex{1a}), the capacitor begins to discharge and electromagnetic energy is dissipated by the resistor at a rate (i^2 R). With U given by Equation 14.4.2, we have [frac{dU}{dt} = frac{q}{C} frac{dq}{dt} + Li frac{di}{dt} = -i^2 R] where i and q are time-dependent functions. This reduces to
Series Resonance circuits are one of the most important circuits used electrical and electronic circuits. They can be found in various forms such as in AC mains filters, noise filters and also in radio and television tuning circuits producing a very selective tuning circuit for the receiving of the different frequency channels.
Figure 23.46 shows an RLC series circuit with an AC voltage source, the behavior of which is the subject of this section. The crux of the analysis of an RLC circuit is the frequency dependence of X L X L and X C X C, and the effect they have on the phase of voltage versus current (established in the preceding section). These give rise to the ...
Objectif : La bobine et le condensateur sont des dipôles qui emmagasinent de l''énergie électrique ou magnétique. Lorsqu''un condensateur se décharge dans une bobine, le dipôle RLC est le siège d''oscillations libres amorties. Quels sont les échanges énergétiques qui se produisent au sein d''un circuit RLC ?
The RLC circuit is analogous to the wheel of a car driven over a corrugated road (Figure (PageIndex{5})). The regularly spaced bumps in the road drive the wheel up and down; in the same way, a voltage source increases and decreases. The shock absorber acts like the resistance of the RLC circuit, damping and limiting the amplitude of the ...
